Exodus 30:11-16
New Catholic Bible
11 The Temple Tax. The Lord spoke to Moses and said, 12 “When you take a census of the number of the children of Israel, each man will offer a ransom for his life to the Lord, when you number them, lest there be a plague among them when you number them. 13 Each person counted in the census will give half a shekel according to the measure of the shekel of the sanctuary (a shekel is twenty gerahs). The half shekel will be an offering to the Lord. 14 Everyone who is counted in the census, from twenty years old and up, will give the Lord’s offering. 15 The rich will not give more and the poor will not give less than half a shekel, when you give the Lord’s offering, in order to ransom your life. 16 You shall take the money of this ransom of the children of Israel and designate it for the needs of the meeting tent. It shall be a memorial before the Lord for the children of Israel, for the ransom of your lives.”
